I do run Firefox (unoficially). the problem is once this virus / worm gets into a network it searches for PCs with weak passwords on their Admin user and tries to login on them - creating a lot of network traffic and sometimes locking out "real" users from their machines - oh and also crashing authentication servers and proxy servers.

Well in our case we hunt down the infected machines, get them off the net (to reduce traffic and to stop further spread), remove the nasty (at least one version of it "hides" as MS Messenger) and put it back on-line.

For you I Guess it should go something like:-1. Clean OS install (are you Windoze or Linux now?)2. Start your anti-virus software3. Load all OS patches - you may have to go on-line for this but there is probably no choice. If you have a fire wall check that nothing unexpected is going in otr out during this period.4. Load all updates for your anti-virus software5. Reboot6. Check for any mal-ware7. Relag i the knowledeg that you'll probably have to do it all again soon.
